I'm trying to get a sense of when people will be available to help on the 20th so I can allocate roles. If you haven't already let me know could you post the details up here?

The day will start at 7:15 with set up, which will be completed by about 9:00. We'll then have a marshal briefing after which marshals will take up their positions.

It would be great to know if you are available for set up, can make it later or have to leave by a particular time. We can then ensure that the set up teams are complete and marshal points are always covered.
